ARBOR-PRESS.

Application filed January 9, 1920. Serial No. 350,425.

To all whom it may concern:

e it known that I, KIRKE R. VVILSON, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Arbor-Presses; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichform part of this specification.

Like figures of reference refer to like parts.

This invention relates to arbor presses, particularly to that classthereof adapted for forcibly putting a gear on a shaft, as well asremoving the same.

One of the objects of this invention is to provide an arbor pressespecially constructed for use of the two operations of putting a gearon a shaft and removing the same, without necessitating any change inthe frame or parts of the press. c

Another object is to provide a serviceable and durable arbor press ofsuch a construction as to adapt the same for use on either a gearedpropeller or a geared axle shaft, of a motor vehicle, thereby providinga press for accomplishing the double purpose of putting a gear onto ashaft and taking the same off, without the use of extra attachmentsordinarily required for changing over the construction of an arbor pressfor one or the other use.

lVith these and other objects, my 1nven tion resides in a combinationand arrange-- ment of parts and details of construction hereinafterdescribed and claimed, it being understood that changes in the oneembodiment of the same herein disclosed, can be made within the scope ofwhat is claimed, without departing from the spirit of the invention.

This one embodiment is illustrated in the accompanying drawings,wherein:

Figure 1 is a plan view of an arbor press embodying my invention.

Fig. 2 is a plan view of the arbor press shown in Fig. 1, but with theparts thereof arranged to push the long shaft out of the gear.

Fig. 3 is an elevation of one of the termitube 7.

nals of the arbor two figures.

Fig. 4, is a side elevation of the arbor ter minals shown in Fig. 3,having part thereof broken away to show the incorporation of a socketpiece therewith.

Fig. 5 is a sectional view of a gear parpress shown in the other tiallyupon thc'shaft, together with a socket in ball bearing connection withthe end of the press screw.

Fig. 6 is a section taken on the line XX of Fig. 1.

.Inthe figures, the terminal ends 1 and 2 are made from like castings,each having an upright portion 3, from the bottom of which extend lugs4', adapted to receive screws or bolts for attaching the press firmly toa sup-. port. Positioned intermediate of the terminal ends 1 and 2, isthe: yoke 5, shown near the end 2. The yoke 5 is spaced from. the

terminal end 2 by pipe or tubing 6, and is spaced from the terminal end1 by pipe or These four pieces are shown in Fig. 1 to be broken away toexpose the long bolt rods 8, having bolt heads 9 and 10, and serve tohold the terminal ends 1 and 2, and the yoke 5 in fixed spaced relation.

In threaded engagement with the terminal 2 is the press screw 11, havingthe usual head 12 and a bar 13 in sliding engagement therewith. The bar13 is fixed in position on the which is positioned the adapting socket19.

Where the socket 19 is positioned concentrically in contact with thegear 18, is a central pocket v20 to receive the end of the shaft A as itprotrudes beyond the gear 18 in itsfinal position. A central pocket 21is provided in the opposite end of the adapting socket 19 to receive injournaled engagement the ball bearing end 22, of the screw 11, having aball 23. The terminal end 1 is provided with a central boss 24, having ahole 25 therethrough. As shown in Figs. 1 and 4, the terminal end 1 isprovided with a plug 26, having a pocket 27.

In Fig. 2, the plug 26 is omitted, leaving a passageway for the end ofthe shaft A, required in removing theshaft from the gear 17. Theposition of the parts shown in Fig.

of spacing pipe head 12 by the setscrew 14, which has a rod upon torepair.

relative position as shown,

attachments for a single 2 represent that taken when the gear is removedfrom the shaft, at which time the ball 23 bears directly upon the end ofthe shaft A, and hub 17 is forced in shouldered contact with the yoke 5.

The operation of the press for putting the gear on the shaft is asfollows: The gear 18 is started upon the shaft A, after which, theopposite end of the shaft A is positioned in the pocket 27 of the plug26, and the shaft is laid in the recess 16 of the yoke 5; the screw 11having been turned out sufficiently to position the adapting socket 19concentrically against the gear 18, after which, the ball bearing end 22of the screw 11 is entered into the pocket 21 until the ball 23 comes incontact with the seat of the pocket, as shown in Fig. 5. The screw isthen advanced, forcing the gear 18 into place on the shaft A, or untilit shoulders against the yoke 5, if the yoke is positioned for limitingthe movement of the gear upon the shaft. The position of the yoke 5 isshown in the figures to be fixed in a position relative to the terminalend 1, for use with a given type of axle or propeller shaft, the case inpoint being that of the Ford type. The purpose of making the parts ofthe press, fixed in is to provide means without any type and size ofshaft and gear, which the ordinary garage re air man is mostly called fcourse, without much changeboth the terminal end 1, and the yoke 5, canbe adjustably fixed in position upon the rods 8, to alter theconstruction slightly for a variety of lengths of shafts and positionsof gears thereon. But the main objects in providing a device of thisnaturehaving its framework parts in fixed relation, is to cheapen itsconstruction and to provide a device which is thoroughly adapted for useon a single type of shaft and gear.

Referring nowto Fig. tion of removing the shaft A from the gear 18, theshaft is positioned to lie in the recess 16 of the yoke5, having the hub17 of the gear 18, in shouldered engagement with the yoke 5, and havingthe shaft A, in alinement with the hole 25, of the terminal end 1', andhaving the ball 23, of the screw in contact with the end of the shaft A.The

2 and the operascrew is then advanced, forcing the shaft A, through thegear 18, to remove the same. Having described my invention, I claim- 1.An arbor press adapted to assemble and disassemble a gear with a shaft,comprising a frame, including terminal members and spacing members, eachof said terminal members having a central core and holes near the outerends of said terminal members, a clamping screw in threaded engagementwith one of said bores, parallel members holding said terminals in fixedspaced relation, a yoke crossing said parallel members and fixed inposition with relation to said terminal members, said screw having aball bearing end for frictionless contact with said shaft when removingthe same from said gear.

2. An arbor press adapted for assembling and disassembling a gear with ashaft, comprising a frame, including two parallel longitudinal members,two end membersin which said longitudinal members terminate, a centralboss with a hole through it on each of said end members, foot legs oneach of said end members for mounting said press upon a support, a crossmember. fixed midway of said end members upon said longitudinal members,said cross member having a central recess open on one side and axiallypositioned with reference to said bosses on said end. members, and ajack screw in threaded. engagement with one of said end members,positioned to be coaxial with both of said end members.

3. Tn an arbor press adapted for assembling and disassembling a gearwith a shaft, -iongitudinal frame, a jack screw in threaded engagementwith one end'of said frame for forcing a longitudinal movement withinsaid frame upon a piece held therein, a pocketed plug releasablyengaging one end of said frame opposite to said screw, an adaptingsocket for engaging concentrically a gear placed with a shaft in saidframe.

for assemblage therewith, said socket being adapted to engage the innerend of said screw, and means for turning said screw to force said gearin place on said shaft and to force said shaft against end contact withsaid plug.
